Best Testosterone Boosters in Australia 2026: 10 Compared

Last updated: September 28, 2026 · Originally published: April 22, 2026 · By Eternal Elixir Editorial

The best testosterone booster in Australia for most men in 2026, on the numbers in this guide, is Eternal Elixir Tongkat Ali 200:1 Extract 2000mg. It costs $39.99 for 90 capsules, each three-capsule serve carries 2,000 mg of 200:1 tongkat ali extract, and it works out at $1.33 a day. Eternal Elixir makes it and it is our pick. Every figure for the other nine products below comes from that brand’s own label or product page, checked in September 2026, so you can test our reasoning against theirs.

If you would rather match the dose used in the only placebo-controlled shilajit trial on testosterone, Emrald Labs Shilajit gives you 500 mg a day for $0.92. If you want the cheapest sensible starting point, Bulk Nutrients ZMA Complex costs $0.62 a day and makes most sense when your zinc or magnesium intake is low. The rest of this top 10 testosterone booster list explains who each product suits, who it doesn’t, and what the human research did and did not show.

Quick answer: the best testosterone supplements in Australia

Our pick: Eternal Elixir Tongkat Ali 200:1 Extract 2000mg ($39.99, $1.33 a day). It gives you the largest tongkat ali serve in this comparison, at $0.67 per 1,000 mg of extract against $2.33 for the next tongkat ali capsule, in a 90-capsule bottle sent from Sydney.

Closest to a trial dose: Emrald Labs Shilajit ($54.90, $0.92 a day), 500 mg of shilajit extract standardised to at least 50% fulvic acid.

Lowest cost per day: Bulk Nutrients ZMA Complex Capsules ($37.00, $0.62 a day), a zinc, magnesium and vitamin B6 formula.

If fatigue and stress are the real problem: Eternal Elixir Korean Panax Ginseng 1600mg ($44.99, $1.00 a day).

A few numbers frame the whole category:

• $0.62 to $2.50 is the range of cost per day across the ten products, at each label’s own serving size.
• 2,000 mg against 500 mg is the gap in daily tongkat ali extract between our capsule and the next capsule down.
• 500 mg a day for 90 days is the purified shilajit dose that raised total and free testosterone against placebo in men aged 45 to 55 (Pandit and colleagues, Andrologia, 2016).
• 90% of 50 “T booster” products in a 2020 analysis claimed to boost testosterone, and only 24.8% had published data showing an increase (Clemesha and colleagues, World Journal of Men’s Health).

Best testosterone boosters in Australia 2026: the comparison table

Every product is set out at its manufacturer’s stated serving size, in Australian dollars. Where a label gives a range, both ends are shown. Prices as of Sep 2026, including any sale price running on the day we checked.

Cost per day is the price divided by the number of label serves in the pack. The Herbs of Gold figure uses the brand’s own price for the 60-tablet pack. It also sells a 30-tablet pack for $51.50, and pharmacies often discount it.

Cost per day hides the dose: cost per 1,000 mg of extract

Two tongkat ali capsules can look alike on a shelf and deliver very different amounts. Emrald Labs uses a 200:1 extract at 500 mg per daily capsule. Eternal Elixir uses a 200:1 extract at 2,000 mg across a three-capsule serve. Same extract ratio, four times the material each day.

So we worked out a second number: what you pay for each 1,000 mg of extract you actually take.

• Eternal Elixir Tongkat Ali 200:1 2000mg: $1.33 a day for 2,000 mg, so $0.67 per 1,000 mg of extract.
• Emrald Labs Tongkat Ali: $1.17 a day for 500 mg, so $2.33 per 1,000 mg of extract.
• ATP Science Tongkat Ali + Shilajit Powder: $2.50 a day for 400 mg of tongkat ali plus 500 mg of shilajit, so the tongkat ali alone would cost $6.25 per 1,000 mg even before you count the shilajit.

Emrald Labs is cheaper per day. Eternal Elixir is cheaper per milligram, by about three and a half times. Which matters depends on whether you want a small maintenance capsule or a full serve.

The same trap applies to shilajit. Emrald Labs gives 500 mg standardised to at least 50% fulvic acid, so at least 250 mg of fulvic acid a day. Eternal Elixir gives 1,000 mg at 20% fulvic acid, about 200 mg. Twice the extract, slightly less of the marker compound. Our shilajit comparison ranked on cost per gram works through the same maths across more brands.

How we ranked these testosterone boosters

Eternal Elixir makes three of the ten products below, and Tongkat Ali 200:1 Extract 2000mg is our pick. It sits first because it gives the largest tongkat ali serve here at the lowest cost per milligram, in a bottle that ships from Sydney. The other nine are ordered on four questions:

• Is there human evidence for the ingredient? Placebo-controlled trials in men count for more than animal work or tradition.
• Is the dose printed per serve? A label that shows milligrams per serve, a standardisation percentage or a dry-herb equivalent beats a proprietary blend.
• What does a day cost at the label serve? We check that against cost per 1,000 mg where two products share an ingredient.
• Can you buy it in Australia today? A product that is sold out or has left its brand’s own store drops out of the numbered list.

What we did not do: we did not lab-test any competitor product, and we have not rated anything on how it “felt”. Where a brand does not publish a number, we say so rather than estimate one. If you want the ingredient background first, our complete guide to tongkat ali in Australia covers extract ratios, sourcing and dosing conventions.

1. Eternal Elixir Tongkat Ali 200:1 Extract 2000mg: our pick

Key specs: $39.99, down from $59.99, for 90 capsules. Three capsules a day on an empty stomach give 2,000 mg of Eurycoma longifolia 200:1 root extract per serve. The only other ingredients are rice flour and a cellulose capsule. Thirty serves per bottle, $1.33 a day, $0.67 per 1,000 mg of extract. Ships from Sydney within 24 hours, free delivery on orders over $100.

Tongkat ali is the herb in this category with the deepest human trial record on testosterone. A 2022 meta-analysis in Medicina pooled five randomised trials and found total testosterone rose with tongkat ali supplementation, and the rise held in the subgroup of men with low testosterone. Our capsule gives you a large, simple serve of that one ingredient, with nothing else in the formula that you would need to research.

The honest qualification: the trials used standardised water extracts at 100 to 400 mg a day, not 200:1 concentrates at 2,000 mg. The two are not interchangeable, and a bigger number on a label is not proof of a bigger effect. What you do get is more tongkat ali extract per dollar than any other product here. Our tongkat ali dosage guide for Australia explains how extract ratios and trial doses compare.

Who it suits: men in their thirties and older who want a full tongkat ali serve rather than a token dose, and who would rather have it sent from within Australia than wait on an overseas parcel.

Who it doesn’t: anyone who hates swallowing three capsules, anyone who wants a single-capsule routine, and anyone who has not yet had a blood test and is trying to fix a problem they have not measured.

Pros

• 2,000 mg of 200:1 extract per serve, four times the next tongkat ali capsule in this list
• $0.67 per 1,000 mg of extract against $2.33 for the Emrald Labs capsule
• 90 capsules per bottle, a full 30 days at the label serve
• Single-ingredient formula with rice flour as the only filler

Cons

• Three capsules a day is more swallowing than a one-capsule product
• $1.33 a day sits mid-pack on raw daily cost
• An extract ratio is harder to compare than a eurycomanone percentage, which this label does not print

Buy it here: Tongkat Ali 200:1 Extract 2000mg, $39.99 for 90 capsules. Our wider tongkat ali supplement comparison covers eight more tongkat ali products sold here.

2. Emrald Labs Shilajit: closest to the dose in the shilajit trial

Key specs: $54.90 for 60 capsules at Elite Supps. One capsule a day in the morning with food, and no more than two in 24 hours. Each capsule holds 500 mg of shilajit extract standardised to at least 50% fulvic acid, in a vegetable HPMC capsule with rice flour and silicon dioxide. $0.92 a day. Elite Supps ships free on orders over $150 and charges $9.90 below that.

This is the only product here whose daily dose lands on the dose tested against placebo for this outcome. Pandit and colleagues gave healthy men aged 45 to 55 purified shilajit at 250 mg twice a day for 90 days, and total testosterone, free testosterone and DHEAS rose significantly against placebo while LH and FSH held steady. That is one trial, so it is a starting point, not a settled result.

Who it suits: men who want their daily shilajit dose to sit on the dose that went through a placebo-controlled trial, and who value a high fulvic acid percentage.

Who it doesn’t: anyone under 16 or pregnant (the label excludes both), anyone with milk, soy, wheat or gluten allergies (the facility handles all four), and anyone who wants a 90-day bottle.

Pros

• Minimum 50% fulvic acid, the highest disclosed standardisation of any shilajit here
• Daily dose matches the trial dose
• Vegetable capsule
• $0.92 a day

Cons

• 60 capsules means a reorder every two months
• Free shipping only starts at $150
• Shilajit is not a substitute for tongkat ali, and the trial evidence rests on one study

3. Bulk Nutrients ZMA Complex Capsules: lowest cost per day

Key specs: $37.00 for 120 capsules, or $35.00 each when you buy four, at Bulk Nutrients. One capsule twice a day, the second before bed. Per capsule: magnesium amino acid chelate 500 mg (100 mg magnesium), zinc amino acid chelate 30 mg (6 mg zinc) and pyridoxine hydrochloride 10 mg (8.23 mg vitamin B6). Vegan capsule. $0.62 a day, with flat $9 shipping from Tasmania.

It is the cheapest product in this list per day, with 4.72 from 173 reviews on the Bulk Nutrients page. The catch is that zinc and magnesium only move hormones when you are short of them. Koehler and colleagues gave ZMA to 14 regularly training men aged 22 to 33 who already ate enough zinc, and serum total and free testosterone did not change. If your diet is thin on zinc and your sleep is poor, this is a sensible first spend. If your intake is already fine, expect little.

Who it suits: men on a tight budget, men whose diet is low in red meat, seafood or legumes, and anyone who wants a bedtime mineral routine.

Who it doesn’t: men who already eat plenty of zinc and magnesium, and anyone who wants a herbal product. The label warns that vitamin B6 can cause tingling or numbness in large amounts or over long periods.

Pros

• $0.62 a day, the lowest in this comparison
• Elemental doses printed, not only the chelate weights
• Large, visible review base

Cons

• A mineral top-up, not a herbal testosterone product
• No hormonal change in men who already get enough zinc
• Two capsules a day, one of them at bedtime

4. Eternal Elixir Shilajit 1000mg: twice the shilajit, 45 serves a bottle

Key specs: $44.99, down from $59.99, for 90 capsules. Two capsules a day on an empty stomach give 1,000 mg of 20:1 shilajit extract standardised to 20% fulvic acid. The other ingredients are a cellulose capsule, magnesium stearate and silica. Forty-five serves per bottle, $1.00 a day. Ships from Sydney within 24 hours.

You get twice the shilajit of the Emrald Labs capsule for a few cents more a day, with a lower marker percentage: about 200 mg of fulvic acid a day against at least 250 mg. The published research is not detailed enough to say whether the fulvic fraction or the whole extract matters more, so neither figure settles it. Where our capsule clearly wins is the bottle. Ninety capsules at a two-capsule serve is a 45-day supply, so you reorder less often, and it sits alongside our tongkat ali in one delivery.

We cover what shilajit does and does not do in our guide to shilajit for men’s energy and performance.

Who it suits: men who want a larger daily shilajit serve and fewer reorders, and anyone already ordering our tongkat ali who wants both in one parcel.

Who it doesn’t: anyone who puts fulvic acid percentage first (Emrald Labs is higher), and anyone pregnant or breastfeeding. The label is for adults only.

Pros

• 1,000 mg per serve, double the Emrald Labs dose
• $1.00 a day with a 45-day bottle
• Arrives in the same parcel as our tongkat ali

Cons

• 20% fulvic acid is lower than the 50% minimum on the Emrald Labs capsule
• Two capsules a day rather than one

5. Emrald Labs Tongkat Ali: simplest one-capsule routine

Key specs: $69.90 for 60 capsules at Elite Supps. One capsule in the morning. Each capsule is 500 mg of 200:1 tongkat ali root extract and nothing else, in a gelatin capsule. $1.17 a day, or $2.33 per 1,000 mg of extract.

The cleanest label here: one active, one capsule, no fillers listed. It beats our tongkat ali on cost per day. It also gives a quarter of the daily extract at about three and a half times the cost per milligram, and that is the trade-off you are choosing between. The label notes that the capsules are made in a facility that handles milk and soy, and the gelatin shell rules it out for vegetarians.

Who it suits: men who want the easiest possible routine and are happy with a smaller daily amount.

Who it doesn’t: vegetarians, anyone with a milk or soy allergy, and anyone comparing on milligrams per dollar.

Pros

• Single-ingredient 200:1 extract
• One capsule a day
• Same-day dispatch from Elite Supps on weekday orders before 1 pm

Cons

• $2.33 per 1,000 mg of extract, three and a half times our cost per milligram
• 60 capsules, so a reorder every two months
• Gelatin capsule made in a milk and soy facility

6. ATP Science Tongkat Ali + Shilajit Powder: both herbs in one scoop

Key specs: $74.95 for a 150 g tub of 30 serves at ATP Science. One 5 g scoop in water gives 400 mg of 200:1 tongkat ali root extract and 500 mg of 15:1 shilajit extract, with berry flavour, citric acid and stevia. $2.50 a day. Free shipping in Australia on orders over $110, and 30-day returns.

Google’s AI Overview named this product for this search when we checked, and the idea is sensible: the two herbs with the best human data in this category, in a drink rather than capsules. The label prints both doses per serve, which many blends do not. You pay for the convenience and the flavouring, though. At $2.50 a day it is the most expensive product in the list, and it gives less of each herb than our Tongkat Ali 200:1 and Shilajit 1000mg together at $2.33 a day.

Who it suits: men who dislike capsules and want one scoop that covers both herbs.

Who it doesn’t: anyone watching cost per day, and anyone who wants to adjust the tongkat ali and shilajit doses separately.

Pros

• Both actives with doses printed per serve
• No capsules to swallow
• Well-known Australian brand with 4.8 from 20 reviews on the product page

Cons

• $2.50 a day, the highest here
• 400 mg of tongkat ali extract a day is a fifth of our serve
• Fixed ratio of the two herbs

7. Eternal Elixir Korean Panax Ginseng 1600mg: for energy and stress load

Key specs: $44.99 for 90 capsules. Two capsules in the morning give 1,600 mg of Korean red ginseng root extract (800 mg per capsule) standardised to 5% ginsenosides. Forty-five serves per bottle, $1.00 a day. Ships from Sydney within 24 hours.

Ginseng turns up in many multi-herb testosterone blends, usually at a small dose. Buying it on its own at a full serve is cheaper per milligram and easier to judge. Be clear about what it is for, though. Ginseng is an adaptogen. Its case rests on energy, mental clarity and how you handle stress, not on androgen production. Plenty of men in their forties who go looking for a testosterone booster have a normal hormone panel and are simply tired and stretched. If that is you, this is the more sensible purchase, and it pairs with tongkat ali without overlapping ingredients. Our Korean red Panax ginseng comparison goes deeper on ginsenoside standardisation.

If you want Tongkat Ali, ginseng and shilajit together, our Daily Energy & Vitality Stack ($109.99) bundles Tongkat Ali 200:1 Extract 2000mg, Shilajit 1000mg and Korean Panax Ginseng 1600mg in one morning routine. Talk to your doctor first if you take any prescription medicine.

Who it suits: men whose real complaint is fatigue and stress rather than a measured hormone problem.

Who it doesn’t: anyone looking for a direct testosterone ingredient, and people who find ginseng stimulating late in the day.

Pros

• 1,600 mg standardised to 5% ginsenosides, a full serve rather than a blend-filler amount
• $1.00 a day, 45 serves per bottle
• No ingredient overlap with our tongkat ali

Cons

• Not a testosterone product: the case is energy and stress, not hormones
• Best taken in the morning

8. Bulk Nutrients Potency Plus: tribulus, KSM-66 ashwagandha and fenugreek

Key specs: $39.00 for 120 capsules, or $34.00 each when you buy four, at Bulk Nutrients. Four capsules a day. Each capsule holds tribulus fruit extract 325 mg (from 6.5 g dry fruit), KSM-66 ashwagandha root extract 150 mg (from 1.875 g dry root) and fenugreek seed extract 125 mg (from 4.13 g dry seed). Per day that is 1,300 mg, 600 mg and 500 mg. Vegan capsules, $1.30 a day, flat $9 shipping.

If you searched for Potency Plus from Bulk Nutrients, this is the product, and it is a fair blend. Every dose and dry-herb equivalent is printed. The ashwagandha dose matches the 600 mg a day that raised testosterone alongside resistance training in young men in an eight-week trial. Fenugreek has a small, very low-certainty effect on total testosterone in the latest meta-analysis. Tribulus, the largest ingredient by weight, did not change testosterone in controlled work in young men.

Who it suits: men who train, want a stress and recovery angle, and like a transparent blend at a fair price.

Who it doesn’t: anyone who wants a tongkat ali or shilajit serve, anyone pregnant or likely to become pregnant (the label says to consult a pharmacist or doctor), and anyone who dislikes four capsules a day.

Pros

• Every dose printed, with dry-herb equivalents
• 600 mg of KSM-66 ashwagandha a day
• 4.55 from 66 reviews on the product page

Cons

• More than half the daily blend by weight is tribulus, the weakest ingredient here for testosterone
• Four capsules a day

9. Herbs of Gold Bulgarian Tribulus Complex: detailed label, thin evidence

Key specs: $82.50 for 60 tablets on the Herbs of Gold site, or $51.50 for 30. One tablet once or twice a day with food. Each tablet combines Bulgarian tribulus herb extract (from at least 4.5 g dry herb) and Indian tribulus fruit extract (from at least 8.7 g dry fruit), standardised to a total of 307.6 mg of furostanol saponins as protodioscin. Free of egg, milk, peanut, soy, gluten and animal products. $1.38 to $2.75 a day at the brand’s price.

This is one of the most carefully specified labels in the category. Herbs of Gold prints plant part, dry-herb equivalence and a standardised saponin figure, which most tribulus products never attempt. The problem is the ingredient. In a controlled study of 21 young men, Neychev and Mitev gave tribulus extract at 10 or 20 mg per kg of body weight for four weeks and found no change in testosterone, androstenedione or LH. Herbs of Gold itself frames the product around libido and sexual function rather than testosterone.

Pharmacy and health-store prices can differ from the brand’s own price, so compare before you buy.

Who it suits: buyers who want full label transparency and are mainly interested in libido support.

Who it doesn’t: anyone buying specifically to raise testosterone.

Pros

• 307.6 mg standardised protodioscin per tablet
• Vegan, free of major allergens
• Simple directions: one tablet once or twice a day with food

Cons

• No effect on testosterone in the controlled trial in young men
• Cost per day doubles at two tablets

10. Emrald Labs Fadogia Agrestis: popular online, no human trials

Key specs: $59.90, down from $69.90, for 60 capsules at Elite Supps. One capsule a day at any time, with a meal if your stomach is sensitive. Each capsule is 500 mg of 10:1 Fadogia agrestis extract in a gelatin capsule. $1.00 a day.

Fadogia agrestis became popular online rather than through trials. The published testosterone work is in rats, starting with Yakubu and colleagues in 2005, and we could not find a placebo-controlled human trial. Animal results do not carry over to people as a matter of course, and long-term human safety has not been established. This is a clean, honestly labelled capsule at a fair price. You are buying on mechanism and anecdote, so size the purchase accordingly. Our fadogia agrestis comparison sets out the animal work and the safety questions.

Our own Tongkat Ali + Fadogia 2010mg is sold out and we do not expect it back soon. For the same goal, our in-stock pick is Tongkat Ali 200:1 Extract 2000mg, ranked first above.

Who it suits: experienced supplement users who understand they are ahead of the evidence.

Who it doesn’t: anyone under 18, pregnant or breastfeeding (the label excludes them), vegetarians, and anyone who wants human data before buying.

Pros

• Single-ingredient 10:1 extract with a printed 500 mg figure
• One capsule a day, flexible timing

Cons

• No human trials on testosterone
• Long-term safety unknown
• Gelatin capsule

Hard to buy right now: ATP Science Ares and Pilot Testosterone Support

Two names that still come up in Australian searches for test boosters did not make the numbered list, because you cannot reliably buy them.

ATP Science Ares was the default Australian answer for years: a vegan capsule blend of tribulus, fenugreek, nettle root and Panax ginseng. ATP Science’s own Ares address now opens a men’s health collection page instead of the product, and the Nutrition Warehouse listing shows it at $69.95 for 90 capsules but unavailable. The brand’s Tongkat Ali + Shilajit Powder at number 6 is the ATP product you can buy today.

Pilot Testosterone Support, from the Australian men’s health service, lists zinc and ashwagandha among its ingredients but no doses on its product page, and it shows $35, down from $45, with “This product is out of stock”. Without a published serve or a stock date there is nothing to compare.

If you came here looking for either of them, the closest in-stock match for a herbal testosterone-support routine is our pick, Eternal Elixir Tongkat Ali 200:1 Extract 2000mg, or Bulk Nutrients Potency Plus if you specifically want a tribulus and fenugreek blend like Ares.

Looking for a Mars Men alternative in Australia?

Mars Men is a US brand that sells a testosterone support formula called Boost. The product page lists 11 ingredients across five capsules a day, taken in the morning with food: tongkat ali 500 mg, shilajit 500 mg, fenugreek 500 mg, cistanche 500 mg, taurine 675 mg, zinc 30 mg, boron 10 mg, vitamin D 4,000 IU and copper 2 mg, plus vitamins K1 and K2. A 30-day supply is US$59 on the brand’s store, which prices in US dollars.

The appeal is obvious: tongkat ali and shilajit in one bottle, with a mineral and vitamin D base. If you want the same two herbs from an Australian seller, our Tongkat Ali 200:1 (2,000 mg a day) and Shilajit 1000mg (1,000 mg a day) give you larger daily amounts of each, cost $2.33 a day together, and ship from Sydney. You can also take them on their own, which a fixed blend doesn’t allow. If you want the minerals too, a zinc and magnesium product such as Bulk Nutrients ZMA adds $0.62 a day. Check the total zinc across everything you take before you stack products.

What the human trials actually measured

The gap between “there is research on this ingredient” and “this product does what the box implies” is where most of this category lives. Here is what the studies behind the rankings found, and what they did not show.

Tongkat ali

• Chinnappan and colleagues, Food & Nutrition Research, 2021. A randomised, double-blind, placebo-controlled trial in 105 men aged 50 to 70 with total testosterone below 300 ng/dL. They took 100 mg or 200 mg of a standardised water extract (Physta) or placebo for 12 weeks. Total testosterone rose against placebo from week 4 in the 200 mg group and by week 12 in the 100 mg group. Free testosterone did not differ between groups. The extract’s maker funded the study.
• Leitão and colleagues, Maturitas, 2021. A six-month, four-arm, placebo-controlled trial in 45 men with a mean age of 47 and symptoms of age-related androgen deficiency. Groups took 200 mg of tongkat ali or placebo, with or without training three times a week. The group that combined training with tongkat ali improved most on erectile-function scores and total testosterone.
• Tambi and colleagues, Andrologia, 2012. 76 men with low testosterone and ageing-male symptoms took 200 mg of a standardised water-soluble extract for one month. The share with testosterone in the normal range went from 35.5% to 90.8%. There was no placebo group.
• Henkel and colleagues, Phytotherapy Research, 2014. A pilot study of 13 men and 12 women aged 57 to 72 who took 400 mg daily for five weeks. Total and free testosterone and grip strength rose. Small and uncontrolled.
• Talbott and colleagues, Journal of the International Society of Sports Nutrition, 2013. 63 moderately stressed adults (32 men and 31 women) took a standardised hot-water root extract or placebo for four weeks. Salivary cortisol fell 16% and salivary testosterone rose 37% against placebo.
• Leisegang and colleagues, Medicina, 2022. A systematic review of nine studies and a meta-analysis of five randomised trials found a significant rise in total testosterone with tongkat ali, including in the subgroup of men with low testosterone.

What these trials did not do: none tested the commercial products in this article, none used 200:1 concentrates at 2,000 mg a day, and most enrolled middle-aged or older men, often with low testosterone at the start. Read together, they point to a modest rise in men who start low, not a transformation in young men with normal levels.

Shilajit

Pandit and colleagues, Andrologia, 2016. Healthy men aged 45 to 55 took purified shilajit at 250 mg twice a day, or placebo, for 90 days in a randomised, double-blind trial. Total testosterone, free testosterone and DHEAS rose significantly against placebo, and LH and FSH were maintained. It is a single trial, and nobody has repeated it at scale.

Zinc and magnesium (ZMA)

Koehler and colleagues, European Journal of Clinical Nutrition, 2009. 14 healthy, regularly training men aged 22 to 33, all with adequate zinc intake, took ZMA. Serum zinc rose, but serum total and free testosterone did not change. The authors concluded ZMA has no significant effect on testosterone in men on a zinc-sufficient diet.

Ashwagandha

• Wankhede and colleagues, Journal of the International Society of Sports Nutrition, 2015. 57 men aged 18 to 50 who were new to resistance training took 300 mg of ashwagandha root extract twice a day, or placebo, for eight weeks while training. Strength, muscle size and testosterone rose more in the ashwagandha group.
• Lopresti and colleagues, American Journal of Men’s Health, 2019. 57 overweight men aged 40 to 70 were enrolled in a 16-week crossover trial using a different ashwagandha extract. Testosterone rose 14.7% more and DHEA-S 18% more than on placebo, but fatigue, vigour and sexual wellbeing did not differ between groups.

Tribulus

Neychev and Mitev, Journal of Ethnopharmacology, 2005. 21 healthy men aged 20 to 36 took tribulus extract at 20 or 10 mg per kg of body weight, or placebo, for four weeks. Testosterone, androstenedione and LH did not differ from placebo.

Fenugreek

Yang and colleagues, Frontiers in Nutrition, 2026. A systematic review of 13 randomised trials found a small favourable effect on total testosterone, no stable effect on free testosterone, and rated the certainty of the evidence as very low.

Fadogia agrestis

Yakubu and colleagues, Asian Journal of Andrology, 2005. A stem extract raised testosterone in male rats. We could not find a placebo-controlled human trial.

The category as a whole

Two analyses of best-selling products explain why this search is hard. Clemesha and colleagues (World Journal of Men’s Health, 2020) looked at 50 “T booster” products: 90% claimed to boost testosterone, the average product had 8.3 ingredients, and only 24.8% had published data showing an increase. Balasubramanian and colleagues (Journal of Sexual Medicine, 2019) reviewed the top five boosters on Amazon and found that of 37 human studies on their main ingredients, 30% showed a rise in testosterone and 46% showed no effect. The Australian men’s health organisation Healthy Male reaches a similar view in its guide to whether testosterone boosting supplements work.

That is why this list leads with single ingredients at printed doses. Sleep, resistance training, body composition and alcohol do more for most men in their late thirties and forties than any capsule. We have written that up as a step-by-step natural testosterone optimisation protocol for men over 35.

The best testosterone booster for men over 40 and over 50

Most of the tongkat ali and shilajit trials above enrolled men in their forties, fifties and sixties, so the evidence fits older buyers better than it fits men in their twenties. For men over 40 in Australia, our pick is the same: Eternal Elixir Tongkat Ali 200:1 Extract 2000mg as the base, with Shilajit 1000mg added if you want a second ingredient that has its own placebo-controlled trial in men aged 45 to 55.

For men over 50, start with a blood test. Total testosterone, SHBG and a morning sample tell your GP far more than any label can, and some causes of low testosterone need medical care rather than a supplement. If your results are in range and your problem is energy, sleep or stress, Korean Panax Ginseng is often the better fit. Our guide to the best supplements for men over 40 in Australia puts testosterone support alongside NAD+ and metabolic health.

Test boosters at Chemist Warehouse and other Australian retailers

Chemist Warehouse is where many Australians start. When we checked its product pages in September 2026, the shilajit options included Wanderlust Shilajit 120 Tablets at $19.49 (RRP $38.99), two tablets a serve with the shilajit amount per tablet not stated, and Lifecykel Shilajit Pure Resin at $92.00, sold online only in a 0.25 g serve. Pharmacy ranges change often, so look for a milligram figure per serve and a standardisation on the label before you buy.

For a standardised tongkat ali extract, a specialist retailer such as Elite Supps or a brand’s own store is the usual route. Eternal Elixir ships from Sydney within 24 hours, with free delivery on orders over $100 and a 30-day money-back guarantee.

Safety: who should not take testosterone boosters

• Anyone under 18, and anyone pregnant or breastfeeding. Most labels in this list exclude them.
• Anyone on prescription medicines, particularly blood-thinning, blood pressure, diabetes or hormone medicines, should talk to a doctor or pharmacist first. Ginseng can interact with some medicines, and tongkat ali has little interaction research.
• Men on prescribed testosterone therapy should not add these products without asking their prescriber.
• Anyone who competes in drug-tested sport should check with their sport’s anti-doping adviser first, because contaminated or mislabelled products are a known risk in this category.
• Anyone who suspects low testosterone should have it measured. None of these products is a substitute for a diagnosis.

Frequently asked questions

What is the best testosterone booster that really works?

Our pick is Eternal Elixir Tongkat Ali 200:1 Extract 2000mg ($39.99), because tongkat ali has the most placebo-controlled human research of any herb in this category and our capsule gives the largest serve here at $0.67 per 1,000 mg of extract. The effect in trials was modest and seen mainly in middle-aged and older men who started with low testosterone. Emrald Labs Shilajit is the closest match to the dose used in the one shilajit trial.

Which brand is best for testosterone boosters in Australia?

Eternal Elixir is our pick for single-ingredient tongkat ali and shilajit in 90-capsule bottles that ship from Sydney, and we make three of the ten products in this comparison. Among other brands, Emrald Labs sells clean single-ingredient capsules, Bulk Nutrients sells the cheapest zinc and magnesium formula and a transparent herbal blend, and Herbs of Gold prints the most detailed tribulus label.

Does any testosterone booster actually work?

Not in the way the category name suggests. No over-the-counter supplement raises testosterone the way prescribed therapy does. The realistic ceiling is a modest shift in men who start low, or who are short of zinc. The trials that did show a change, purified shilajit at 500 mg a day for 90 days and standardised tongkat ali extracts in older men, enrolled middle-aged participants, not healthy young men. If your energy, libido or mood has changed noticeably, a blood test with your GP comes first.

How can a 40 year old man increase testosterone?

Start with the basics that have the strongest evidence: regular resistance training, enough sleep, losing excess body fat, and keeping alcohol low. Get a blood test so you know your starting point. If your levels are low-normal and you want a supplement on top, tongkat ali is the ingredient with the most human data, and zinc only helps if your intake is short. Our natural testosterone protocol for men over 35 sets out the steps in order.

What is the best testosterone booster at Chemist Warehouse?

When we checked Chemist Warehouse product pages in September 2026, its shilajit options included Wanderlust Shilajit tablets ($19.49), which do not state the shilajit amount per tablet, and Lifecykel Shilajit Pure Resin ($92.00, online only). Look for a printed milligram dose per serve and a standardisation. For a standardised tongkat ali extract you will usually need a specialist retailer or a brand’s own store. Our tongkat ali buying guide covers what Australian retailers carry.

How much should a testosterone booster cost per day in Australia?

Across the ten products checked in September 2026, the range was $0.62 to $2.50 a day at each label’s own serving size. Work it out from the serving size, not the capsule count. A 120-capsule bottle at four capsules a day lasts 30 days, not 120.

What dose of tongkat ali did the human trials use?

The randomised trials used standardised water extracts at 100 to 400 mg a day, not the 200:1 concentrates sold in most capsules. A 200:1 ratio describes how much raw root went in, while a standardisation percentage describes how much marker compound comes out, so the two are not interchangeable. Our guide to how long tongkat ali takes to work covers the trial timelines.

Is Bulk Nutrients Potency Plus a testosterone booster?

Bulk Nutrients describes Potency Plus as a blend for virility, energy and stress, not as a testosterone product. It combines tribulus, KSM-66 ashwagandha and fenugreek at printed doses. The ashwagandha dose matches a trial where testosterone rose alongside resistance training, the fenugreek evidence is weak, and tribulus did not change testosterone in a controlled study in young men.

Does Fadogia agrestis have human evidence behind it?

Not that we could find. The published testosterone work on Fadogia agrestis is in rats, and animal results do not automatically transfer to people. Long-term human safety has not been established either, so if you buy it, buy it knowing that.

The verdict: which testosterone booster should you buy in Australia?

Our pick for most men: Eternal Elixir Tongkat Ali 200:1 Extract 2000mg, $39.99 for 90 capsules, $1.33 a day and $0.67 per 1,000 mg of extract. It gives four times the daily extract of the next tongkat ali capsule at under a third of the cost per milligram, and it ships from Sydney within 24 hours.

If you want the dose that went through a shilajit trial: Emrald Labs Shilajit, $54.90, $0.92 a day. If you would rather have a larger shilajit serve in a 45-day bottle, our Shilajit 1000mg costs $1.00 a day.

If you want the cheapest sensible start: Bulk Nutrients ZMA Complex Capsules, $37.00, $0.62 a day, most useful if your zinc or magnesium intake is low.

If fatigue is the real problem: Eternal Elixir Korean Panax Ginseng 1600mg, $44.99, $1.00 a day.
